DETAILED DESCRIPTION OF THE INVENTION

Hereinafter, a specific embodiment of the present disclosure will be described in detail with reference to the accompanying drawings.

FIG. 1 is a front view illustrating a distributing panel according to an embodiment of the present disclosure, and FIG. 2 is a perspective view illustrating a distributing panel according to an embodiment of the present disclosure, and FIG. 3 is a front view illustrating an inside of a distributing panel according to an embodiment of the present disclosure, and FIG. 4 is a front view in which a distributing panel according to an embodiment of the present disclosure is disassembled.

The distributing panel may include a base frame 1, a transformer panel module 2, a high voltage panel module 3 and a low voltage panel module 4 as illustrated in FIGS. 1 through 4.

The distributing panel may be an integrated distributing panel in which the base frame 1, transformer panel module 2, high voltage panel module 3 and low voltage panel module 4 are integrally assembled, or an outdoor integrated distributing panel in which they are installed and used outdoors.

The distributing panel may include a switch 31, a transformer 21 and a distributor 41 as illustrated in FIG. 3. The distributing panel may receive high voltage power through the switch 31, and step down the high voltage power to low voltage through the transformer 21, and supply power to each power consumer through the distributor 41.

The distributing panel may dispose the switch 31, transformer 21 and distributor 41 over the high voltage panel module 3, transformer panel module 2 and low voltage panel module 4 in a distributed manner.

The high voltage panel module 3 may include the switch 31, and the transformer panel module 2 may include the transformer 21, and the low voltage panel module 4 may include the distributor 41.

For the distributing panel, the transformer panel module 2 may be installed on the base frame 1. The high voltage panel module 3 and low voltage panel module 4 may be fabricated separately from the transformer panel module 2, and assembled to be fastened to at least one of the transformer panel module 2 and base frame 1.

The high voltage panel module 3 provided with the switch 31, the transformer panel module 2 provided with the transformer 21, and the low voltage panel module 4 provided with the distributor 41 may be respectively and independently fabricated and then combined, and the high voltage panel module 3, transformer panel module 2 and low voltage panel module 4 may be fabricated to respectively have a protection degree and then integrally combined.

The high voltage panel module 3, transformer panel module 2 and low voltage panel module 4 may be fabricated such that a protection degree (IP rating, International Protection) of any one module of them is different from that of the other modules.

The high voltage panel module 3 provided with the switch 31 and the low voltage panel module 4 provided with the distributor 41 may respectively require higher stability than that of the transformer panel module 2 provided with the switch 31.

On the contrary, the transformer panel module 2 provided with the transformer 21 may require a relatively low protection degree in consideration of the cooling performance of the transformer 21 or the like.

The protection degree of the high voltage panel module 3 and the protection degree of the low voltage panel module 4 may be fabricated to have a higher protection degree than that of the transformer panel module 2. For example, the high voltage panel module 3 and low voltage panel module 4 may be fabricated to satisfy IP54 or above, and the transformer panel module 2 may be fabricated to satisfy IP31 lower than that of the high voltage panel module 3/low voltage panel module 4 in consideration of the cooling performance of the transformer 21 or the like.

The low voltage panel module 4 may have a low voltage enclosure 42 coupled to the other side of the main frame 22 and a distributor 41 disposed within the low voltage enclosure 42.

The distributing panel allows the switch 31, transformer 21 and distributor 41 to be installed together within one case. However, in this case, it is not easy to fabricate at least one of a portion surrounding the switch 31, a portion surrounding the transformer 21 and a portion surrounding the distributor 41 within one case with a different protection degree from that of the other portions, and when all the switch 31, transformer 21 and distributor 41 are installed within one case, a long period of time may be required for fabrication time. Furthermore, when an accident occurs within one case, the entire one case should be replaced or a long period of time will be required for maintenance.

As in the present disclosure, when the high voltage panel module 3, transformer panel module 2 and low voltage panel module 4 are individually configured and assembled with one another, it may be easy to fabricate them with a different protection degree for each module, thereby reducing entire fabrication time through segmentation for each module as well as facilitating maintenance or replacement.

Furthermore, when part of the high voltage panel module 3, transformer panel module 2 and low voltage panel module 4 is changed to a different protection degree, only necessary modules may be replaceable without exchanging the entire distributing panel, thereby having an advantage of reducing cost.
